Question

the perimeter of a rectangle is 130cm and its width is 28cm. find the area of the rectangle.. wat does this mean............

Answer 1

anyone??

Answer 2

The length of all sides of the rectangle adds up to 130cm. The given width is 28cm, so 28cm * 2 = 56cm, so two sides of the rectangle add up to 56cm. That leaves us with 74cm (130 - 56) for the other two sides. And 74 / 2 = 37cm.

So, the top and bottom of the rectangle are 37cm each, and the left and right sides are 28cm each.

To get the area of a rectangle, you multiply the length and width together, so in this case the area is 37*28 which equals 1036cm^2.

So the answer = 1036cm^2.

Answer 3

(130- 2*28)/2 * 28
1036cm^2

Answer 4

^ That works too. Haha

Answer 5

P=2(w+l)
130=2w+2l
130=2*28+2l
130=56+2l
130-56=2l
74=2l
l=74/2
l=37

-so than width is 28 cm and the lenght is 37 cm

area = 28*37 = 1036 cm^2

Answer 6

P = 2L + 2W
A = LW

first of all find L

L = (P-2w)/2
so L = (130-2(28)/2
L = 130 - 56/2
L = 74/2
L = 37
so A = 37 x 28
A = 1036 cm^2
